U.S. Senator Al Franken has been very vocal about his Apple opinions for years, and this time he’s sent a letter to Tim Cook regarding Touch ID in the iPhone 5s.

Franken has “substantial privacy questions” when it comes to Touch ID’s security, and given the recent NSA findings, his concerns come at a time when the American public’s questioning of online security has heightened.

It’s safe to say the general consensus is againstAT&T charging for FaceTime over cellular in iOS 6. The carrier is expected to introduce some sort of fee for Apple’s video calling service this fall, and AT&T has been trying its best to keep the issue quiet for as long as it can. While you would still be able to use FaceTime over a WiFi connection, carriers like AT&T obviously doesn’t want a bunch of video calls hogging everyone’s bandwidth.

Minnesota Senator Al Franken has been very vocal in the tech scene for years. He famously emailed Steve Jobs about the iPhone tracking debacle back in 2011, and he has continued to stand up for consumer privacy rights with the carriers and companies like Carrier IQ.

Franken recently spoke out on AT&T potentially charging its subscribers for FaceTime over cellular, noting that it would be flat-out “wrong.”

Sen Franken wants to know why Apple is collecting the data; how it is collected; what it is used for; why it isn’t encrypted; if the data is shared; and why consumers aren’t asked before the data is collected.
